Infielder Gavin Lux was added to the Loons from the Dodgers’ extended spring training in Arizona.

McKinstry, 21, was drafted out of Central Michigan University by the Dodgers in 2016 and hit .261 in 41 games for the Loons last year. He was also a member of the postseason roster that won the Midwest League championship.

Lux, 19, is from Kenosha, Wis., where he played prep baseball at Indian Trail High School. He was selected in the first round (20th overall) by the Dodgers in last year’s MLB First-Year Player Draft. Originally committed to play at Arizona State, Lux spent time in the Arizona and Pioneer Leagues in 2016 after signing. In 56 total games, he hit .296 with 18 extra-base hits and 21 runs batted in.
